Improvement in pumps for locomotive-tenders



4UNITED STATES PATENT OFFICE A, WT. TODI), OF CHICAGO, ILLINOIS.

IMPROVEMENT IN PUMPS FOR. LOCOMOTIVE-TENDERS, &C,.

Specification forming part of Letters Patent No. 45,360, dated December6, 1864.

To all whom it may concern.-

Be it known that I, A. I/V. TODD, of the city of Chicago, county ofCook, State of Illinois, have inventeda new and Improved Mode of Raisingor Forcing Water; and I do hereby declare that the following` is a fulland exact description thereof', reference being had to the accompanyingdrawings, making part of this specification, in which- In Figure 2,Arepresents a well to he made large in proportion to the demand of water,and to be sunk deep enough for the water to rise above the valve J, sothat the water will llow in suilicient quantity to till the cylinder Kup to said letter J. It' the cylinder K is entirely submerged, so muchthe better. 'Ihus it will be seen that when the valve O is raised by therope l on windlass I to the hoop N, as seen above the cylinder K, `andis sufficiently weighted with any material, and released, all the waterbeneath it is forced up and through pipe L, the valve J being closeduntil valve O passes it, at which moment it opens, and the water rushingon top the valve O will add weight at the precise moment when it is mostwanting or needed. rIhe cylinder K is made stationary by means ot' theframes G G G by two simple wedges, M M. It is ex.- pected that the wellwill be 'curbed and the posts I) l) spiked to it.

As the cylinder K sits on the bottom ofthe well, a suitable foundationshould be provided to keep it from sinking when the bottom of the wellis soft.

The transverse bar H is to keep the rod 2,

which raises valve O, in its place, secured by as suitable strip, asseen at H.

The weight P, swung over the windlass I, is intended to bring the valveO to its proper place when hoisted to its upper position.

The valve O is madeA suiliciently large for the quick egress ot' thewater above it, thus y making but little resistance in 'being hoisted.rI`he iron hoops, as seen at G G G G, Fig. 2

` one at bottom and one at top-are to secure the frames G G G to thecylinder K.

In case either or both of the valves O and J should need repairing, itmay be done by removing the wedges M M and transverse bar II. Thecylinder K, frames G G G, and pipe L may all be raised above water bymeans of a rope being attached to the frames G G G and over windlass I.

The valve J can be screwed ott' and easily repaired.

Cylinders may be made of any desirable size, from two to six feetdiameter by six or eight feet high, and placed in wells, cisterns, orany place where the water will rise to valve J, and the water may beforced to any height by adding weight to hoop N, as the diameter ofcylinder and height the water is required to be raised requires, and sosoon as the valve O reaches the bottom all the water in pipe L runsback, thus all trouble and expense caused by freezing is avoided, as itis not expected for any water to be raised only as it is wanted forimmediate use.

C, Fig. 1, represents a drum or pulley of sufficient size to draw upwith ease whatever weight may be swung to the windlass I, to which it isattached.

rIhe ropes T T, which operate the drum C, are passed around the pulleysF F, Fig. 2, which are made stationary, one on each side ot' the well atany desirable distance from it, and at the proper distance from therailroadtrack, so that as the locomotive passes slowly by the hook S isattached to it and carried as far beyond F as the hook Sis beyond F, asseen at Fig. l, dotted line. At the saine time the hook S is drawn to 3,Fig. l, ready to be attached to the return of the locomotive or trainthat may come the other way.

The drum C is intended to be attached and detached to wiudlass I by theship and unship arrangement, by which arrangement the windlass I andhoop N run back without revolving the drum G. Thus the rope arrangementis kept in tact, and in case two or more trains should be going thesaine way the pulley C and ropes T T and hooks S S are easily put C inproper position by hand.

'lhe hooks S S, when drawn by the locomotive to the proper point, aredetached like the weight ot' a pile-driver, at which moment the pulley Cis caught by the lever E at fulcrum E, and held till the water is readyto be received, when it is unshipped` from the windlass I, whichrevolves back, letting down the hook N and valve O, thus forcing thewater through pipe L, while the drum C remains quiet, &c. Care shouldalways be taken not to entirely release the windlass I and hoop N untilthe valve O is known to be in contact with the water, as in case of lowwater the valve O might be drawn above it, and if let fall would producea bursting shook in all probability. The shield r, on the valve O, nextthe valve (or opening)J is to preventthe Water from passing around Whilethe valve O is passing the inletvalve J. The opening V is the exit o1Water into pipeL,Whiehis shown to be passed by valve after all the wateris diven up through said pipe L, thus allowing I am aware that therehave been many plans for raising Water 5 but What I claim, and desiretoseeure by Letters Patent, is-

The combination and arrangement of the welll A, cylinder K, frames G GGr, Wedges M M, hoops G Gr G G, pipe L, valves O and J, hoop N, rope andWeight P, rod 2, transverse bar H, orifice V, Windlass and rope I,stanohions or posts D, pulley C, with ship and unship arrangementpulleys F F, ropes TT, ooks S S, lever E, and fulorum E, sills B,

substantially upon the principle and iu the manner herein set forth.
